Overview
The Microchip Technology 1N4758AP/TR8 is a Zener diode with a nominal voltage of 56 V and a power dissipation rating of 1 W. It features a ±5% tolerance and operates within a temperature range of -65°C to +150°C. The device utilizes an axial DO-41 package and exhibits a maximum reverse leakage current of 5 µA at 42.6 V. Its maximum Zener impedance is specified at 110 Ohms, with a forward voltage drop of 1.2 V at 200 mA.
Feature Summary
- Provides stable voltage regulation at 56 V with high precision ±5% tolerance
- Engineered for robust operation across extended industrial temperature ranges
- Constructed in a standard axial leaded package for through-hole mounting
Applications
- Voltage reference circuits requiring precise 56 V levels
- Overvoltage protection stages in electronic systems
- General-purpose voltage regulation tasks
Procurement Notes
Verify the specific suffix AP/TR8 against official Microchip documentation to confirm tape-and-reel packaging and exact electrical tolerances. Confirm RoHS compliance status as datasheets may vary by revision. Ensure the component meets all environmental specifications required for the intended operating conditions before finalizing procurement decisions.
Selection Notes
Select this component when a 56 V Zener voltage with tight ±5% tolerance is required. The 1 W power rating supports moderate current applications. The axial DO-41 package facilitates easy integration into through-hole designs. Verify that the 110 Ohm impedance and 5 µA leakage current meet the specific circuit requirements.
Part Context
This part belongs to the 1N47xx series of Zener diodes manufactured by Microchip Technology. These components are widely used for voltage regulation and reference applications. The 1N4758 variant specifically targets the 56 V market segment within the broader family of axial-leaded semiconductor devices designed for reliable performance.
Replacement Considerations
Public confirmed substitute part numbers: 1N4758A-TP (MCC), 1N4758 G (Microchip). Verify pinout compatibility and electrical parameter alignment before substitution.
